PDMLink Basic concept – eBOM and mBOM contexts

Historically, Windchill proposes to use the “view” concept in order to manage mBOM Parts as it provides the following advantages:

• Allow to manage different BOM’s for the same Part (eBOM versus mBOM)

• Allow to manage different values for the same attribute of the same Part

• Allow separate configuration and approval between eBOM and mBOM for the same Part

• Allow concurrent work on eBOM and mBOM for the same Part

• Allow the re-use of eBOM parts into mBOM parts based on view network.

• Allow a traceability on the revision level between eBOM and mBOM using the revision label

PDMLink Basic concept – View Hierarchy

• Windchill organizes views as a hierarchy

– A “New View Version” creates a downstream part version• Design Manufacturing• Manufacturing Plant 1• Design Plant 2

– Parts can be initially created in any view– New View Version can only go downstream

• By default the hierarchy has two views, Design and Manufacturing (EBOM and MBOM)

View Limitation – Assembly Splitting

– When an assembly is split, new Part Numbers are created in mBOM

– View mechanism cannot anymore ensure traceability/change process (Based on Part Number)

View Limitation – Renumbering

– Some customer are re-numbering Parts when creating their mBOM

• e.g. document based eBOM– View mechanism cannot anymore ensure

MPMLink Key Concept – Equivalent link: Definition

– To over come the view mechanism limitations, MPMLink has introduced the Equivalent Link concept

– Definition: It relates an iteration of an upstream Part (eBOM) to its equivalent downstream (mBOM) iteration.

MPMLink Key Concept – Equivalent link: Purpose (1/3)

– Purpose: the Equivalent Linkprovides “associativity” between an upstream Part and its equivalent downstream one, for supporting:

• Traceability and Conformity• Change Processes• Concurrent Product and Process

MPMLink Key Concept – Equivalent link: Context

– For the Equivalent Link, the context is a pair of Views e.g. upstream context = design view and downstream context = manufacturing view. (Upstream context can be the same as the downstream context or be empty)

– The same Part can have different equivalent Parts depending where it’s used in mBOM

Equivalent link: Features

– The Equivalent Link has a direction and it’s owned by the downstream iteration

– The Equivalent Link is a 1-N or N-1 relationship meaning one upstream iteration can have multiple downstream equivalent Parts and vice versa

– Upstream versus downstream contexts should (strongly recommend) follow the network view so that it is possible to reuse upstream Parts is into downstream BOM’s

– When a new iteration of a linked downstream Part is created, the Equivalent Link is duplicated

– When a new iteration of a linked upstream Part is created, no Equivalent Link is duplicated (Out-of-date)

27


– When an Equivalent Link is updated for a downstream Part:

• the system proposes to display differences between latest version and the currently linked iteration

• a new Equivalent Link is created to the latest upstream iteration

– In future, the Equivalent Link could be used to propagate modifications from Upstream to Downstream

Report differences between associated BOMs

• Quickly identify quantity discrepancies between associated BOMs– Compare two or more structures and supports multi-level comparisons– Part quantity comparison analysis using the associativity links– Highlight parts in Creo View or in the Process Plan Explorer– Displays quantity comparison results in a color coded table, which can be easily navigated by

discrepancy type (equal to, greater than, less than)

29

Status Indicator for Equivalent Link (1/3)

– Indicators in Product Structure tree are used in order to asses the status of the Equivalent Links.

– Equivalent Links Status:• No Equivalent Link exist

MPMLink Key Concept – Equivalent Occurrence Link

– Definition: The Equivalent Occurrence Link relates an occurrence of Part in an upstream context to its equivalent occurrence in an downstream context. (Path to Path Link)

– Purpose: To allow monitoring discrepancies on the occurrence level between a downstream BOM and its upstream equivalent one.

33

Paste with Associative BOM Links (1/2)

– Allow to transform eBOM into mBOM by picking eBOM Parts and pasting them into mBOM.

– Copy of eBOM Partscan be done from any eBOM Tree (Selection or another Explorer) or from 3D but the paste with associative BOM Links is only possible in the tree

34

Paste with Associative BOM Links (2/2)

– When pasting an eBOM part into an mBOM assembly – If an equivalent part exists for the downstream context, the system will reuse that equivalent Part.– If no equivalent link exist, then the system displays a panel for the user to specify:

• If a new view version is needed (“New View”)• If a completely different Part is needed (“Duplicate”)• If the Part should be used as is (“Same”)

– If an assembly has been pasted as-is (“Same”) in mBOM, associative BOM links are created only on pasted assembly, not on the children.

Equivalent iteration in downstream found and

will be re-used

35

Creo View for Windchill MPMLink

– “Creo View for Windchill MPMLink” can read information from Manufacturing Product Structure Explorer:

• Structure: Leaf .ol positioned with values from the occurrence

• Upstream Equivalent Part• Downstream Equivalent

Occurrence• Upstream Equivalent Occurrence• Common Parent• Representation

Digitally define and manage process plan in WindchillMPMLink:

– Define plant-specific process plans with multiple sequences of operations (supporting sub-operations, parallel and alternates)

– Define different process plan types (machining, assembly, quality, maintenance, repair,…)

– View the in-process state of assembly at any operation using embedded Creo View 3D visualization

– Define process plan operations by allocating parts, manufacturing resources, skills, documents, operator instructions and time/cost breakdowns

– Reuse the same process plan to manufacture multiple parts (example for variant parts or left/right hand parts)

– Define alternate process plans for the same part– Reuse standard process plans from a standards

library
